[Ulnar nerve-hypothenar muscle H-reflex in a child with SLE (author's transl)].
In the hypothenars of a 14 years old boy with SLE an abnormal H-reflex could be elicited by ulnar nerve stimulation. Beyond infancy this phenomenon has only been described in patients with lesions of the higher cervical spinal cord and/or the lower brain stem and in children with Sydenham's chorea. There might be reason to assume, that in alike auto-immune disorders the search for an H-reflex in the hypothenar might be useful in detection of cerebral involvement.
